10 Ramadhan 1437
The idea that we can improve ourselves, spiritually and morally, lies at the heart of the experience of fasting. In this respect there is no real end to the fast as, genuinely accomplished, it should spill over into the rest of one's life, and be built upon in subsequent Ramadhans, assuming God's mercy allows us to experience these.
But progress is always problematic. The teacher who writes making steady progress on your report is never being entirely honest, as every student knows.
